First Female CEO of NASDAQ Credits All-Girls School With Preparing Her for Success

Yet another successful woman is pointing to the unique all-girls educational environment as critical to her for success—Adena Friedman, NASDAQ CEO and president, says her time at an all-girls school "made a difference" and prepared her for a career on Wall Street.

Speaking on an episode of CNBC's "Life Hacks Live," Friedman said, "I could feel that it was OK to be smart, and that I really loved math and science, and so I was able to really propel myself into those fields and not really have any of those sort of social pressures that sometimes co-ed environments can create. So I really actually loved being in an all-girls school... I do think it (attending an all-girls school) did help me create a sense of confidence and realizing that I could be as strong and as smart as anyone else in the room."
